In regulatory governance cycle, policy evaluation has become an institutional practice to evaluate the effectiveness and efficiency of regulation once it is in force. The relevance of this cycle’s phase refers to the evaluation of the effects and impacts of regulation considering the direct, indirect or unintended effects. Particularly, evaluation should not be confused with “monitoring” or “audit” actions; evaluation is a systematic and analytical assessment, addressing important aspect of policies, regulations, organizations and programmes.
A close link should be formally established between ex ante and ex post phases and be embedded in the regulatory impact assessment. Moreover, effective consultation with stakeholders ensures that reviews are effective and increases the transparency and accountability in public institutions.
Though the ex post evaluation is generally appreciated among governments, the diffusion of this practice remains sporadic within the OECD countries and it has not yet been implemented in a systematical way.
The OECD Policy Outlook describes also some possible approaches for setting evaluation framework and their use in practice.
